Welcome to $sitename!
$sitename is powered by Pepperminty wiki, a complete wiki in a box you can drop into your server.
Navigating
All the navigation links can be found in the top right corner, along with a box in which you can type a page name and hit enter to be taken to that page (if your site administrator has enabled it).
In order to edit pages on $sitename, you probably need to be logged in. If you do not already have an account you will need to ask $sitename's administrator for an account since there is not registration form. Note that the $sitename's administrator may have changed these settings to allow anonymous edits.
Editing
$sitename's editor uses a modified version of slimdown, a flavour of markdown that is implementated using regular expressions. See the credits page for more information and links to the original source for this. A quick reference can be found below:
